The Yankees recently picked up southpaw Mike O'Connor on a minor league deal. O'Connor, who is now 31, has pitched in 35 major league games; he made appearances for the Nationals in 2006 and 2008 and spent some time with the Mets last year. Only one of his major league games since 2006 has been a start; the Yankees will look at him strictly as a reliever with Damaso Marte and Pedro Feliciano going down with injuries.

We have 14 games and 14 2/3 innings' worth of PITCHf/x data on O'Connor. As little as overall performance metrics mean with this kind of sample, individual pitch type metrics mean even less, so I won't spend too much time on that stuff.
